Question for the tire guru's

[somewhereinusa]

I got a set of 6 really good Michelin XRV tires for FREE, mine are a bit scary weather checked on the sidewalls. The only problem is they are a bit smaller. I've made up a
spread sheet to see road speed differences. This is the final result. Any comments? Do you think the difference is something I can live with?



Thanks,

your chart shows the new tyres will have you driving either slower to save the engine , or at higher revs to get to the destination in the same time .

which do you prefer.

There is a very big load rating difference - how much weight you got there?? That could be a problem if you are more than about 33,000 lbs.

Gotta love the fact they are Michelin....
